As noted elsewhere, i think it would be inappropriate to not allow anyone called GUEST to post. Mudcat gets a lot of people who come in to ask a question and are unaware of local conventions regarding simple politeness. When told, they either get a cookie or adopt a cognomen if they want to stay around. ANON.GUEST, of course, deserves a phaser blast up his internet connection for his/her/it's childish flaming/trolling activities. Could whoever has the current line to Captain Kirk please arrange that?
